Mobula Ray Snorkeling in Cabo San Lucas: Swim with Migrating Rays (May–July)
Witness thousands of mobula rays migrating off Cabo San Lucas—an intense, three-hour snorkeling excursion (May–July) that combines the Arch, a sea lion colony, and multiple chances to enter the water with these acrobatic rays.
The Experience
Before You Go
Bring reef-safe sunscreen
Protect the marine environment—apply reef-safe sunscreen before arrival and reapply with a towel on board rather than in the water.
Treat seasickness proactively
Take an antiemetic the night before or two hours before departure if you’re prone to motion sickness; mornings are usually calmer.
Follow guide signals in the water
Guides will assess ray behavior and current—only enter when instructed and keep fins and hands controlled to avoid startling the animals.
Use a snug mask and fins
A well-fitting mask prevents leaks and fogging during multiple submersions; fins increase maneuverability in current.

Conservation Note
Operators recommend reef-safe sunscreen, no-touch policies, and limiting in-water time to minimize stress on the rays and surrounding marine life.
Cabo’s Arch formed from millions of years of wave-cut erosion and marks the meeting point of the Pacific and Sea of Cortez, long a passage for fishermen and mariners.
Photographer's Notes
- • Bow of the boat during approach to the school

Common Questions
When is the best time to see mobula rays?
Mobula ray migration is most consistent May through July; morning departures often offer calmer seas and better visibility.
Do I need to be an expert snorkeler?
No—basic snorkeling skills and comfort in open water are sufficient; guides will pair less confident swimmers with extra support and limit entries based on conditions.
Is gear provided?
Yes—all snorkeling equipment, soft drinks, snacks, and guide fees are included. Many guests bring their own masks for fit and comfort.
Can children join the tour?
Infants can ride in a stroller prior to boarding and must sit on an adult’s lap; operators assess each child’s ability to safely participate in snorkeling.
What wildlife might I see besides mobulas?
Common sightings include California sea lions, dolphins, and occasionally sea turtles; whales are less common during the peak mobula season.
What is the cancellation policy?
Full refunds are available if canceled at least 24 hours before departure; the operator may cancel for bad weather or insufficient travelers with a refund.
